Scope

Main Technical Content: This standard specifies the terms and definitions, classification, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of oil-based markers. The main items of this standard are set based on the principles of advancedness and practicality, while significantly raising the requirements on the basis of industry standards. Compared with QB/T 2777-2015 "Markers", the main changes are as follows: - Improved requirements for initial writing performance from 100mm to 50mm; - Improved requirements for writing performance from 100m to 200m; - Improved requirements for leak resistance from -10kPa to -30kPa; - Improved requirements for drying time from 1 minute to 30 seconds; - Improved requirements for adhesion from 4.9N to 5.9N; - Improved requirements for intermittent writing from 30 minutes to 1 hour with ink discharge within 50mm; - Added safety requirements for end caps; - Increased the limit of migratable elements in ink from 8 to 18 items; - Added limit requirements for harmful solvents in ink; - Added phthalate ester indicators. Determination Basis: This standard is a recommended standard, primarily compiled based on the technical requirements of QB/T 2777-2015 "Markers". The limit values for harmful substances in this standard refer to the requirements for phthalate ester limits in the REACH Regulation of the European Union and standards such as EN 71-3 and T/CWIA 1001. Compared with international and industry standards, this standard has improved the writing performance and environmental friendliness of products. This standard adds new requirements for the migratable content of specific elements, limits for harmful substances such as phthalate esters in ink, and limits for harmful solvents in ink. The migratable content of specific elements and the limits for harmful solvents in ink are routine testing items in European and American markets. Long-term intake of th
